Error code P2526 - clio 4

[Gear]

So i was at my Service Center and got my Clio updated both the Gearbox and ECU to the latest versions
8000 A482 for the ECU
5500 0842 for the Gearbox

Driving home after work with these updates made a huge difference at least for the gearbox. Sport mode the shifts now were instant, no lag at all. as soon as the paddle was pressed it was in new gear, very responsive !

I did notice that in normal mode the car revved little bit higher but not much, and the brake peddle was little bit stiffer, but everything felt very good, almost as it was different car

But when i got home i saw that i have an error code P2526
(scanner used Rstuner, car is not mapped yet - just used it to read ecu data now)

p2526
Vacuum Reservoir Pressure Sensor Circuit Range/Performance

no ide what this is, anyone with some more knowledge who could explain more ?

*ment to say sport mode, post updated

Using ELM 327 OBD reader doesn't show any fault codes, and reading up on the rstuner manual (online) this fault code i got is not an Renault fault code.
It is something else regards to the rstuner that only Henk can give an answer to.

Was out yesterday for a longer drive and pushing it a bit
The car runs better than ever before after the updates. Normal mode is great now! And sport even better.

Almost never in race mode so cant compare how it was before really.
